This is probably a common problem among all the people trying to get audio over HDMI under Linux using an EN210 graphics card (or similar).
Even though the HDMI may appear in your available cards listed in proc (/proc/asound/cards) you will probably see that you cannot find it using the aplay utility. Just check it running the command “aplay -l”. The HDMI device isn’t listed here isn’t it?
The reason for this issue is related to the ALSA driver version 1.0.21 (or older) which is quite buggy for these graphics cards.
You can check which version you are using by executing the following command:
If you get a version older than 1.0.21 then you need to upgrade it. You can check your favourite distribution’s repository for an update or you can try to compile it from source code.
If you can’t find an update, check this page: http://ubuntuforums.org/showthread.php?t=1681577

If you are running the latest version of Ubuntu and tried to mount a NTFS filesystem you probably already know that you can’t and maybe you have even seen an error like “mount exited with exit code 21″.
This seems to be due to a bug in libfuse2 and/or fuse-utils package. To fix this temporarily you can downgrade both packages to a prior version. libfuse2 and fuse-utils version 2.8.1-1.1ubuntu2.2 seem to be OK but 2.8.1-1.1ubuntu3.2 is useless.
Just download both packages and install them:
Don’t forget that these are 32bit packages. If you are using 64bit OS then download the needed packages.
sudo dpkg -i libfuse2_2.8.1-1.1ubuntu2.2_i386.deb
sudo dpkg -i fuse-utils_2.8.1-1.1ubuntu2.2_i386.deb
If you are an Android Developer you probably know how hard it may be to develop webservices based applications. The lack of official support for these implementations is compensated by some modules like ksoap2 that handle de SOAP stuff and communication.
For simple cases where you just have to send/receive simple data types it is easy to use, but things can get a bit complicated when you need to handle complete data types with dozens of different functions.
That’s why someone created the automatic stub generator. A stub is a set of classes generated automatically from the WSDL so you don’t have to create all functions, definitions and data types available in the WSDL by hand.
You can download the ksoap2 jar from here.
You can download the stub generator from here or you can try my online version of the stub generator filling the input box with the WSDL URL and press download.
